Description
Large stopper with hole for weighing cups, 18 × 24 × 30 mm in grey, is a laboratory accessory for secure seating of weighing cups during balance work and sample preparation. The dedicated opening lets a weighing cup pass through the stopper so the cup stays centred and stable while filling, taring or transferring material. The 18 × 24 × 30 mm large-format profile is easy to handle with gloves, and the grey finish supports quick visual sorting among other stoppers and fittings on a busy bench. Supplied as a single piece, it suits teaching labs, quality-control stations and routine analytical weighing where a simple mechanical interface between stopper and weighing cup is required. This accessory comes from manufacturer Dinkelberg and contains no electronics or chemistry—only a purpose-shaped stopper for everyday laboratory material use. The hole geometry helps reduce tipping and spillage when the cup-and-stopper assembly is moved between the balance and the work surface, making it a practical choice for repeated small-sample workflows under controlled laboratory conditions.
This article is part of Sample containers & jars, in Bottles & containers.

Questions about Stopper large, with hole for weighing cup, 18x24x30mm, color GREY
What is this article?
Stopper large, with hole for weighing cup, 18x24x30mm, color GREY is the article on this page. Luminix Health distributes Dinkelberg for laboratory use. It sits in Sample containers & jars, inside Bottles & containers, in Labware.
A sample container or jar is the vessel the sample travels in, with a closure that survives the trip. The volume and the liner decide whether the sample that arrives is the sample that was taken.
A laboratory bottle is a closed container with a stated volume and a neck that takes a cap, a stopper or a dispenser. Borosilicate glass is the choice when the liquid is a solvent, or when the bottle will be heated or autoclaved. Polyethylene and polypropylene are the choice when the bottle must not shatter, or when hydrofluoric acid would attack glass. A narrow mouth pours. A wide mouth is for powders and for reaching the bottom. Laboratory ware of this kind is indexed under ISO laboratory glassware. Traceable volume sits with the BIPM and NIST Physical Measurement.
